Indian Space Research Organisation chairman G Madhavan Nair on Tuesday said that there is no satellite in the world that can predict a tsunami. Similarly, there are no scientific tools to predict an earthquake either.

But satellites can provide images capturing the trail of disaster caused by a tsunami for assessment and fast tracking relief operations.

"We have positioned our remote sensing satellites on the entire affected region and are constantly updating the Crisis Management Group [based in Delhi] with images," Nair told PTI in Bangalore on Tuesday.

But ISRO immediately positioned the 5.6 metre high-resolution cameras of Resourcesat and the panchromatic cameras of the IRS satellites to map the disaster, which claimed thousands of lives and destroyed villages along the coast.
